This data set contains cosmogenic nuclide surface exposure data from Dronning Maud Land, East Antarctica and relative sea levels are calculated based on original and refined ICE6G ice-load models, presented in "Regional sea-level highstand triggered Holocene ice sheet thinning across coastal Dronning Maud Land, East Antarctica".
To clarify the mass and heat balance, snow depositional condition on ice sheet, AWS was installed at H128. The H128 Automatic Weather Station (AWS) Data Graph provides a variety of real-time data, including air temperature, relative humidity, wind speed, wind direction, up and down shortwave radiation, up and down longwave radiation, surface air pressure, snow height, snow temperature, and more. The H128 site is located on coastal Dronning Maud Land, East Antarctica (69.4S, 41.57E, 1380 m a.s.l). This AWS is maintained and operated by JARE/NIPR.
Airborne radar data collected during the PolarGap project funded by the European Space Agency. The radar system PASIN of the British Antarctic Survey was used for data collection.
Measurements of sea ice thickness, sea ice concentration, water temperature/salinity profile, and water current profile. Monitoring of vessel movement during ice navigation.

Abstract:
During the austral summer of 2015/16, a major international collaboration funded by the European Space Agency (ESA) and with in-kind contribution from the British Antarctic Survey, the Technical University of Denmark (DTU), the Norwegian Polar Institute (NPI) and the US National Science Foundation (NSF), acquired ~38,000 line km of aerogeophysical data. The primary objective of the POLARGAP campaign was to carry out an airborne gravity survey covering the southern polar gap of the ESA gravity field mission GOCE, beyond the coverage of the GOCE orbit (south of 83.5degS), however aeromagnetics and ice-penetrating radar data were also opportunistically acquired. This survey covers the South Pole and Recovery Lakes, as well as parts of the Support Force, Foundation and Recovery Glaciers.
Our Twin Otter aircraft was equipped with dual-frequency carrier-phase GPS for navigation, radar altimeter for surface mapping, wing-tip magnetometers, an air-sea gravity meter, and a new ice-sounding radar system (PASIN-2).
We present here the full radar dataset consisting of the deep-sounding chirp and shallow-sounding pulse-acquired data in their processed form, as well as the navigational information of each trace, the surface and bed elevation picks, ice thickness, and calculated absolute surface and bed elevations. This dataset comes primarily in the form of NetCDF and georeferenced SEGY files. To interactively engage with this newly-published dataset, we also created segmented quicklook PDF files of the radar data.
NOTE: Please note that an issue with the floats in the NetCDF variable "UTC_time_layerData" has resulted in this variable having rounded up decimal numbers. In order to fix this issue, we advise users who need this variable to download the separately published bed pick data for the POLARGAP survey (doi: https://doi.org/10.5285/d55e87dd-a74d-4182-be99-93ab805103ab) and use the ''DateTime_YYYY-MM-DD_HH:MM:SS.S'' column which is the same as the one used to produce the NetCDF.

Abstract:
The dataset contains 12 new Be-10 cosmogenic nuclide surface exposure ages. The samples were collected from a scoria cone 1.5 km west of Mt. Murphy an exposed volcanic edifice adjacent to Pope Glacier in the Amundsen Sea Embayment, Antarctica. Samples of erratic cobbles which showed evidence of transport by ice were collected over the 2015-2016 AmuNdsen Sea Embayment Exposure Dating (ANISEED) Field Season, prepared at the CosmIC laboratory, Imperial College London and measured for Be-10 at the Australian Nuclear Science and Technology Organisation. Beryllium-10 concentrations were measured by Accelerated Mass Spectrometry (AMS). Samples were measured to determine timing of deglaciation of two rock outcrops to better constrain the ice sheet lowering history of Pope Glacier during the Holocene. Study forms part of the wider International Thwaites Glacier Collaboration Project (ITGC). Samples were collected by Dr. Joanne Johnson and Dr. Stephen Roberts (British Antarctic Survey), supported by field assistants Alistair Docherty and Iain Rudkin. Sample preparation for 10Be measurement was carried out by Jonathan Adams - PhD candidate affiliated with British Antarctic Survey/ Imperial College London under the supervision of Dr. Dylan Rood - Imperial College London. AMS measurements of Beryllium-10 concentrations were performed by Dr. Klaus Wilcken - Australia''s Nuclear Science and Technology Organisation (ANSTO).

Abstract:
The ESA PolarGap airborne gravity, lidar/radar and aeromagnetic survey was carried out in Antarctica in the field season 2015/16.
The purpose of the 2015/16 ESA PolarGAP airborne survey of the South Pole region was to fill the gap in satellite gravity coverage, enabling construction of accurate global geoid models. Additional radar flights over the Recovery Lakes for the Norwegian Polar Institute (NPI) were carried out as part of the same survey, but included collection of airborne gravity. Gravity data were collected using two complimentary systems. The primary system was a ZLS-modified Lacoste and Romberg (LCR) gravimeter (S-83) which gives exceptionally low and predictable long term drift. The secondary system was high specification inertial navigation system (iMAR RQH-1003), provided by TU Darmstadt, capable of resolving gravity anomalies even under turbulent conditions, but more prone to instrument drift. Results from both systems were merged to give a unified best product.
The aircraft used was the BAS aerogeophysicaly equipped twin otter VP-FBL.

Abstract:
The dataset contains satellite L* values, last closed drift shell (LCDS) model locations and model magnetic field values for three two day periods covering three different magnetic storms. The periods covered are 27-28 February 2014, 22-23 June 2015 and 14-15 December 2015. The L* values are calculated for electrons with a pitch angle of 90 degrees at the locations of the GOES-13, GOES-15 and HIMAWARI-8 geostationary satellites, using the IRBEM library with the TS05 and TS07 external magnetic field models. Magnetic field values from the models are also included for the GOES-13 satellite during the June 2015 event. LCDS values for each of the periods are included, with two LCDS models based on the TS05 and TS07 field models, and a third LCDS model based particle tracing simulations.

Additional radar flights over the Recovery Lakes for the Norwegian Polar Institute (NPI) were carried out as part of the same survey. In conjunction with the primary datasets aeromagnetic data was collected opportunistically, to provide new insights into the subglacial geology.
Data were collected using a caesium magnetometer system, and have been corrected to total field values following the approach laid out by the SCAR ADMAP working group (http://admap.kopri.re.kr/ADMAP-2_SCR_27Aug13.pdf).
The aircraft used was the BAS aerogeophysicaly equipped twin otter VP-FBL.
